post-partum complications Flashcards
What does ARM stand for?
Artificial rupture of membranes
What does EFM stand for?
Electronic field monitoring– this is the belt around the belly used to monitor fetal condition
what is fFn?
Fetal Fibrinectin. This is a test used to establish likelihood of labour in the next 2 weeks. If +ve, we know that mom is likely to go into labour within the next 7 days. If -ve, babe will likely stay in utero for the next 14 days.
What is a non-stress test?
A test completed during pregnancy to observe how the baby is handling activity ie when mom exerts herself
What does “station” refer to?
baby’s head in relation to the ischial spine. Right at the ischial spine = 0
What is effacement?
Thinning of the cervix
How is effacement different in a primip as compared to a multip?
P- effacement happens before the cervix opens,
M- effacement and opening occurs simultaneously
What gestational age is considered “pre-term”?
36 weeks + 6 days
What is considered “full term”?
37 weeks - 41 weeks + 6 days
What is considered “post term”?
42 weeks +
In order to be officially “in labour”, mum must be having what 3 things?
4 contractions q20mins, needs to be 2cm dilated, and 80% effaced
What puts mom at risk for experiencing pre-term labour? (Demographic, physical, preg. problems, DOH)
Demo: age, low SE status, ethnicity
physical: hx of pre term labour, genetics, uterine/cervical or placenta abnormalities
preg.:PROM, fetal anomalies, hydramnious, HIP
DOH: tobacco/drug use, inadequate weight gain, poor nutrition, stress
What is the significance of using nifedipine when a mom is at risk for experiencing pre-term labour?
it is a calcium channel blocker, and therefore works by inhibiting contraction of smooth muscle, which stops contraction of the uterus, slowing down labour
What is the role of progesterone injections for those at risk for pre-term labour?
projesterone is a hormone that causes the uterus to relax, which can help slow labour down
When is is appropriate to administer tocolytic medications to a mom at risk for pre-term labour?
up to 32-33 weeks
What is the goal for administering corticosteroids to moms at risk for delivering pre-term babes?
help to promote lung development in the babe to help reduce the risk for respiratory distress syndrome in premie babes. *DO NOT GIVE if >34 weeks
If your patient starts to go into premature labour, describe the necessary nursing care,
- assess contractions and per-vagina loss
- monitor babe
- Assess for side effects of meds
- Give corticosteroids (per MAR) to increase lung maturity of babe
- Prepare for premature birth, including phoning to NICU to advise
What are some possible causes for moms going post-term?
- error in determining ovulation and conception
- deficiency in placental estrogen (this causes a subsequent decrease in prostaglandin and decrease in oxytocin receptors in myometrium)
- continued secretion of progesterone
what are some potential MATERNAL problems when anticipating a post-term delivery?
- psychological stress
- induction
- shoulder dystocia
- assisted deliver
- perineal trauma (large babe)
- increased risk of infection and hemorrhage
- risk for c section
- risk for DVT
What are some potential FETAL complications with post-term deliveries?
- decreased placenta profusion
- fetal demise
- oligohydramnious
- macrosomia (lg babe)
- meconium aspiration
- low apgar
- SIDS
- cerebral palsy
If your patient is 41 weeks pregnant, what sort of medical interventions should they expect before the baby comes?
- daily fetal movement counts
- bi-weekly non-stress tests
- ultrasound for fetal size and amniotic fluid index
Why, based on moms condition, might the doctor consider inducing mom?
- post term
- diabetes
- HIP
- PROM
- chorioamnionitis
- previous precipitous L&D
Why, based on babes condition, might the doctor consider inducing mom?
- demise
- hemolytic disease
- macrosomia (lg babe)
- mild abruptio placenta
When considering induction, what scoring tool is used? What is the difference between a “ripe” cerix and an “unripe” cervix?
Bishops score
Ripe= >6
Unripe= <6
If cervix is unripe, what are some medical interventions to help promote cervical effacement?
- intracervical prostaglandins
- cervidil
- cervical ripening balloon
If cervix is ripe, what are some medical intervention to help induction?
- membrane sweep
- amniotomy (break the water)
- intravaginal prostaglandin or IV oxytocin
How does a ripening balloon work?
like a foley, insert it, expand it, and it disrupts the cervix because it causes natural secretion of prostaglandins (same idea as having sex)
After your patient has been induced, what is the expected nursing care?
- Baseline assessment (vs, vaginal exam, electronic fetal monitoring)
- Follow dr orders re: protocol
- Assess pr and
fetus q 2 hrs - if cervidil/prostaglandins, pt may be sent home until active labour begins
What is the difference between augmentation and induction?
A-occurs when mom is in active labour but is experiencing ineffective contractions
I- occurs when drugs are given to help promote or bring on labour
Artificial rupture of the membranes can be very effective in helping promote active labour, but it also comes with some risks. What are these?
- may shorten labour, possibly increasing the risk of tearing
- increased pressure on the head of the baby
- may increase the risk of infection
- increased risk for emergency c-section
While monitoring the baby, you notice a decrease in baby’s O2. What could possibly be causing this?
- cord compression
- placenta insufficiency
What are some warning signs for fetal distress?
meconium stained liquid is OMINOUS– obserce fetal heart rate patterns
When your baby is in distress, what are the most appropriate nursing actions?
- Stay calm*
1. d/c induction
2. change position to lateral
3. IV bolus
4. Vaginal Exam
5. O2 PRN
6. decrease maternal anxiety
7. fetal scalp blood sample
Forceps and Vacuum extraction is only appropriate for what stage of labour and delivery?
2nd
Why might Doc consider forceps or vacuum delivery?
MOM- exhaustion, lack of progress, health conditions, decreased motor function with epidural
BABE- distress, placenta separation, OP position (face up), large baby, breech
